"Grassy" Spike Rush (Eleocharis acicularis) aka "Thread Grass" or "Sterile Thread-Like Leaf"
Updated: May 14
Some species of Spike Rush are erect and emergent, while others, like the one shown here, are more grass-like and submergent. The submersed species of this plant often form large areas of “grassy” bottom growth, with stems reaching lengths of 1-2 feet. "Grassy" spike rush is common in shallow portions of the lake.
